Preheat your oven to 400°F (200°C).
Cut the bell peppers in half, remove the seeds, and arrange them in a large baking dish.
Heat olive oil in a skillet over medium heat. Add the diced shallot and sauté for about 5 minutes, or until it becomes translucent.
Stir in the minced garlic and chopped broccoli, cooking for another 5 minutes until the broccoli turns bright green.
Add the shredded rotisserie chicken, cooked rice, oregano, salt, pepper, and half of the shredded mozzarella and cheddar. Stir to combine, allowing the cheese to melt into the mixture.
Gradually stir in the water or chicken broth, starting with 1/2 cup. Add more as needed if the mixture seems too dry.
Spoon the mixture into the halved bell peppers. Top with the remaining cheese.
Cover the baking dish with foil and bake for 30 minutes. Afterward, uncover and bake for an additional 15-20 minutes, or until the peppers are tender.
Remove from the oven and sprinkle with crushed crackers and freshly chopped parsley. Serve and enjoy!
